Abstract: | This paper covers three aspects of electrochromic smart windows. Their energy efficiency is discussed, and it is argued that
a control strategy considering whether a room is in use or not can lead to large savings of the energy needed for space cooling.
With regard to durability, it is shown that chemical compatibility between the electrolyte and electrochromic films of tungsten
oxide and nickel oxide can be achieved without loss of optical transparency. Finally, we consider device manufacturability
and present data on precharging of electrochromic nickel oxide films by ozone treatment.
